IMPROVEMENT IN SAMPLE-ENVELOPES.

Specification forming part of Letters Patent No. 179,871, dated July 18, 1876; application tiled January 2, 1875. I

To all lwhom it may concern:

Be it known that I, CHAs. E. SAWYER, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Im provementsin Sam ple-Envelopes, of which the following is a specification:

The object of my invention is to increase the strength of the edges of envelopes used for conveying samples by mail or otherwise; and it consists in the means employed for connecting together and for strengthening the edges of the envelope, substantially as hereinafter fully specified.

Figure 1 represents an elevation, showing my invention partially attached to the edges of an envelope. Fig. 2 is a similar view, showing the binding attached for connecting to gether and strengthening` the envelope.

A represents the front portion, and A the rear portion, of an envelope. These two parts are cut from a strip of paper, and placed together, as shown. In order to connect the edges of the two parts 'AA' together, but more particularly to increase the strength of the envelope and prevent its edges from becoming torn during transmission, a binding of cloth, B, is placed over the edges of the two parts A A and folded down, as shown in Figs. 1 and 2, and secured thereto by gum, paste, or other adhesive material, and extending in one continuous piece or strip around three edges or sides of the parts A,A,forn1ing the envelope, being turned around the corners without being cut, the overlapping corners of the strip B being gummed or pasted down, thus securing the corners of the envelope against the liability of leakage when iiour or tine pul- -Yerized drugs, or like materials, are being transported in such envelopes by mail or otherwise.

By constructing the sides or parts A A of paper, so as to be addressed or written upon with pen and ink, and covering their edges with a binding of cloth or stronger material, B, which, when folded together at the open end, as shown b v the dotted lines, Fig. 2, forms a kind ot' margin or frame around the envelope, which gives it a neat appearance, as well as rendering suchvery strong at the coi" ners and edges, where most wear and tear comes when in use for the purposes` designed.

I am aware that paper bags have been made heretofore ot' two sheets of paper, and united together upon three of their edges by means of three narrow strips of paper folded over the edges ofthe bag, andl pasted to the same, one strip upon each edge meeting at the bottom corners of the bag; but I am not aware that a single strip has been used to unite the three edges by being turned Whole around the corners in one continuous piece without cutting, thus securing the corners firmly.

Having thus described my invention, what I claim is- As a new article of manufacture, a sampleenvclope as made of paper, having its sides and end secured together and strengthened by means of an outer adhesive binding, ex-

4tending' around its corners without being cut,

substantially as and for the purposes specified.
